Free Mobile Meta Checker

Over half of searches happen on phones — and a missing viewport tag breaks the entire experience. NToolHub's free Mobile Meta Checker audits the mobile-critical tags in your HTML: viewport, theme-color, web-app capabilities and touch icons. Mobile SEOs run it on every template before launch.

Tip: right-click a page → “View page source”, copy it, and paste it here. Nothing leaves your browser.
Private by design. This tool runs 100% in your browser — your content is never uploaded to any server.

How to Use the Mobile Meta Checker

  1. Paste the page HTML and click Analyze.
  2. Make sure the viewport tag uses width=device-width without disabling zoom.
  3. Add theme-color and an apple-touch-icon for a polished mobile experience.
  4. Re-check after fixing to reach a full score.

Features

Paste HTML for six automated checks — viewport correctness (including zoom-blocking detection), theme-color, Apple/mobile web-app-capable flags, apple-touch-icon and charset — with a scored report and plain-language fix guidance.

Benefits & Use Cases

Correct mobile meta tags are the foundation of mobile-friendliness: proper scaling, branded browser UI, and installable-app behavior. Since Google is mobile-first, these tags directly affect how your pages are evaluated.

Tips

Always use width=device-width, initial-scale=1 without disabling user zoom (blocking zoom is an accessibility failure), add a theme-color matching your brand, and provide a 180×180 apple-touch-icon.

Frequently Asked Questions

What does the viewport meta tag do?

It tells mobile browsers how to scale the page. Without width=device-width, phones render the desktop layout shrunk down — unreadable without pinch-zooming.

Should I disable user zoom?

Never. Disabling zoom (user-scalable=no, maximum-scale=1) is an accessibility violation that harms low-vision users and can hurt mobile usability scores.

What is theme-color?

A meta tag setting the browser UI color (address bar on Android, etc.) to match your brand — a small polish detail that makes sites feel native.

Do I need apple-touch-icon?

Yes if you care about iOS users adding your site to their home screen. Without it, iOS uses an ugly screenshot thumbnail.
